Enhancing role breadth self-efficacy: The roles of job enrichment and other organizational interventions

Role breadth self-efficacy (RBSE) refers to employees' perceived capability of carrying out a broader and more proactive set of work tasks that extend beyond prescribed technical requirements. A newly developed scale of RBSE was internally consistent and distinct from the related concepts of proacti ve personality and self-esteem. In an initial cross-sectional study (N = 58 0), work design variables (job enrichment, job enlargement, and membership of improvement groups) were the key organizational predictors of RBSE. Thes e investigations were repeated in a second cross-sectional study (N = 622) and extended by examining change over time (N = 459). The longitudinal anal ysis showed that increased job enrichment and increased quality of communic ation predicted the development of greater self-efficacy.
